Use a load-line analysis for the PMOS amplifier shown in Figure P11.24 to determine the maximum, minimum, and Q-point values of vo(t). The characteristics of the transistor are shown in Figure 11.9 on page 565.
2. A load of 8Ω is supplied by a single-switch Direct Current (DC) chopper with an inputvoltage of 40V. The switching frequency is 800Hz, the duty ratio is 0.4, and thetransmission voltage drop of the transistor is 2.4V
a. Draw the chopper circuit presented in the question
b. Find the switching period with the duty time of BJT
c. Draw the load voltage, load current, BJT current, BJT voltage along two periods
d. Find the output voltage. Is the achieved load voltage the average value or the effectivevalue e. Find the output power f. Find the average value and effective value of BJT current g. Find the power loss of BJT h. Find the DC source current i. Find the circuit efficiency
Please answer as soon as possible. I'll upvote it. Thanks. Consider a two-BJT configuration in Figure 1. You may assume that both transistors are the same with the same β, VBE,on = 0.7 V, and VCE,EOS = 0.3 V. Derive the DC current gain AI = IC/IB in terms of β for the two-transistor circuit. You may assume that β is large.
